A SpringBack install. If you have all the necessary Cydia packages installed all ready, like 5 column springboard, then you just copy all the blanks and SpringJumps included and restore from the SpringBack file. It takes about 5 minutes to install if you already have the Cydia packages installed, and about 10-15 if you need to install them. You will have to arrange your extra game/tool apps to your liking manually, though.

i dont have cycorder as i have a 3gs so should i still use springback because it says not to use if you dont have a previously uninstalled app

It should be fine, if you are really concerned, make a backup before installing. You could also make a backup after installing then restore from it so you use your own icon layout. I think that would prevent any ill effects.
